ADJUSTING MEANS FOR WRAPPING-MACHINES.

Specification of Letters Patent.

Original application filed August 19, 1912, Serial No. 715,745. Divided and this application filed October 15,1915. Serial No. 56,076.

J '0 all whom it may concern:

Be it known that 1, WILLIAM C. S'rnvmvs, a c1t1zen of the United States, and a res dent of the city of Akron, in the county of Sumniitand State of Ohio, have invent ed certain new and useful Improvementsin Adjusting Means for Wrapping-Ma- OlllllQSi; and I do hereby declare that the following is a full, clear, and exact description of the sanie, reference being had to the accompanying drawings, and to the numerals of reference marked thereon which form a part of this specification.

.Thisapplication constitutes a divisional application of my co-pending application for patent for wrapping machines, filed August lQ, 1912, Serial No. 715,745.

This invention relates'in particular-to the specific adjusting. mechanism for the -justment to adapt the machine for wrapping annular bodies of diil'erent sizes permitting' the elements of the machine to be quickly and readily adjusted to accommodate an article therein.

It is also an object of this invention to provide a means for positively supporting and rotating an article to be wrapped and for adjusting said supporting and rotating means relatively to one another and to the wrapping machine.

It is finally an Ob eot of this invention to construct a Wrapping 'niachine provided with an improved form of adjusting means for adjustment of the supporting and driving rollers on which an article is 'placed before wrapping.

The invention illustrated in the drawings more fully described.

(in a preferred form) is and hereinafter On the drawings:

Figure 1 is a side elevation of a wrapping nachine embodying the principles of my invention.

Fig! 2 is a central transverse section thereof wlth parts shown in elevation.

Fig. 3 is a top plan view of the machine with parts in section and parts omitted.

As shown in the drawings:

The reference numeral 1, indicates a relatively low base or table supported upon a suitable frame or legs 2, and having a central longitudinal slot thercthrough. Journaled transversely of said table on the top thereof is a driving shaft 3, having at the outer end thereof tight and loose belt pulleys 4 and 5, respectively, adaptingvthe shaft to be driven from any suitable source of power.

Mounted upon said table at one side of saidcentral slot, is an upright crescentshaped frame 6, which, as shown, is rigidly bolted to said table with the arms of the crescent directed upwarr lly and outwardly or forwardly as clearly shown in Fig. 1. Rigidly secured upon said driving shaft 3, is a belt pulley 7, having a double peripheral flange 8, projecting oircumfcrentially therearound aiiordiun a grooved periphery to receive a bolt 9, trained therein.

Jourualed longitudinally of the table on each side of said belt pulley 7, in bearings 10 and ii, are shafts 12 and 13, each having eccentric portions extending through sleeves 14, and eachsleeve provided with upwardly directed front and rear blfllflx'lil'ill'IIlS 15 and 16, respectively. Said sleeves and eccentrics are normally heldlc rotate together by means of set screws 87. Journalcd through the upper ends of each pair of bracket arms 15 and 16, are shafts 17, having groove rollers-l8, rigidly secured thereon. Said shafts 17, at their rear ends are provided with sprocket wheels 10, about which are trained,sproclget-chains 20, which are also trained about sprocket wheels 21, rotatably mounted on the ends of the respective shafts 12 and 13. integrally or otherwise rigidly connected with each of said sprocket wheels 21, are worin gears 22, also rotatable on said respective shafts l9. and 13, and each in mesh with "one oil. two wornis 23; on said d iving shaft 3, so that rotation of said drive shzvlt 3, acts through the medium of said, respective Worms zincl Worm gears and, sprocket Wheels chains to rotate the groo'v'ecl feed rollers 18.

Means are provided for adjusting said oed or advancing rolls toward anal ii'vvziy ron'z one nnoiher For this purpose, as shown, El (lovvnwo filly directed. arm 2%, is provided. 02; each sleeves 1 1', and carried in the lower end of each of said zari'ns is a not 213', through "which extends a; screw shaft 26, which is pivoizilly mounteii in. a. bearing}; .27, on the frame or table. Rototion of one of said screw shafts acts on. die nut 25 to swing the eorres wmling advancing or feed roll outwardly or inwardly, dependent upon the direction of rotation, thus 'onobiing eiiher or hol-h of said ailvmioing and ii iii rolls l8, be adjusted So the most eliieient position for suppm-ting and rota?- ingr or advancing the ar'iiole to be Wrapped. Outward adjustment of said feed rolls ohviously porniics the supported object to he supported soinewlmt lower in the machine, while inward adjustment of the feed rolls supports said articles higher in the nmol'iine.

Mounted on said. grooved driving piiliey 7, with fiat periphery iiiting in the groove in the periphery of said driving pub ley is an annular shuttle 28, which is mounted vertically transversely of e tire or other body to be. wrapped. Jonrnoiecl on die foe-mini arm of the crescent frame 6, at its extremiiy grooved pulley .Zfinnii on the other or rear arm of Sil-iLi crescent "frame (3, another grooved. pulley 3G, Said grooved pulleys and 30, receive the periphery oi the annular shottle28, in the grooved peripheries thereof while said shuttle is supported on the grooved driving pulley, said shufitlo thus being ex'igngeel at three points at substantially equal distances apart, permittinf the shuttle to rotate freely therewith and therobetween. The belt 9, trained about the grooved driving pulley 7, is also trained about the grooved pulley 30, and downwardly around a port of the periphery of the shuttle 28, and. then over the pulley 29, thereby operating to rotolze the slnittle. A hinged section 31, is provided in said shuttle 28, to permit opening thereof to receive an article to be Wrapped. inserted therein, and suitable locking means is provided to lock the some in closed position, the details-fol which, however, since they form no part of this invention, being.

omitted from the iiescription.

A reel of paper 32, is mounted at a convenient point upon the shuttle 28, opposite the hingod section '31, of the shuttle, and rototes around With'the shuttle, feeding the paper upon an. article being Wrapped. Mounted, upon the table at the rear of the shniizle enol rigidly secured in a bracket 33,

is :1 standard 34, ocljusiabiy seourerl on.

, agziinso which the lop of lire or other annular llOLlY to be W1 oped rests and i7! els during the Wrapping operoiion. 'ifhe n ljust-moot according to the size of rho h iv to be Wrapped is accomplished by adjusting the mfivzmeing or feeding rollers 18, inwardly or outwardly toward. or away from. he sliuitle by mean i of the screw sioiil's 26.
